Why Is My Air Conditioner Blowing Hot Air?
When the temperature is high in Minnesota, the last thing you need is more hot air. But on occasion, your air conditioner (AC) malfunctions and can turn your home into a stuffy inferno.

Hot air coming from your ductwork is a serious comfort issue. We’re here to help!
As a friendly reminder, change your air filter once every three months. Operating with a clean filter prevents circulation issues and promotes healthy indoor air quality (IAQ), which is especially important during allergy season.
According to the U.S. Department of Energy (DOE), your air conditioning unit runs up to 15 percent more efficiently with a clean filter.
Why Is My AC Blowing Hot Air?
Several factors that could be at play in your Minnesota home. Here are a few common culprits:
Clogged AC Filter
A filter obstructed with dust and debris stifles airflow. That leads to weak circulation, making your home feel warmer, no matter how much you adjust the thermostat. Even worse, it can overwork your equipment, leading to reduced efficiency mechanical problems, and full-scale breakdowns.
We’ve said it before, and we’ll say it again––remember to change your filter.
The thermostat is the boss of your entire HVAC system. If it gives the wrong orders, your AC will work improperly. Your thermostat should sit in a central location of your home. If it’s located in a cool or drafty area, your AC will think the desired temperature has already been reached. Be sure to have your HVAC specialist can move the thermostat to an appropriate place. Programming or wiring issues could also be at play.
When ice or frost forms on your evaporator coils, it is called a “freeze-up.” The coils circulate refrigerant, which is how your air conditioner removes heat and humidity from the air. Freeze-ups prevent this process from taking place.
Frozen coils are often caused by an obstruction. It could be blocked air ducts, a clogged filter, or a dirty fan. Or the coils themselves may be dirty.
These are all signs of inconsistent maintenance. Remember to schedule seasonal checkups. Our Precise Heating, A/C, Plumbing and Refrigeration team makes maintenance convenient and reliable for St. Joseph area homeowners like you. You’ll enjoy significant discounts, priority service, friendly reminders, and other perks.
Your indoor and outdoor AC components play a critical role in cooling your home. The outdoor compressor generates cool air; the indoor component circulates it. If the outdoor unit is powered off or not working, your blowers may be circulating non-conditioned air.
Other Mechanical Problems
Sometimes, the issue is slightly more complex. If the cause is not one of the previous items, it could be the following:
- Broken compressor
- Referent leak
- Electrical error
